Venous thrombosis is a dangerous disease, especially for large thrombus, it is not easy to thrombolysis, because if the thrombus falls off, it will enter the lungs with blood, block the pulmonary artery, cause pulmonary embolism, and lead to suffocation and sudden death. Even a small thrombus can be treated with thrombolysis under the guidance of a doctor.
Guiding opinions:
You'd better have an examination first to see how big the embolus is, and then follow the doctor's advice. If the thrombus is large, it can be removed surgically, which is safer. In addition, it will be difficult to do this without strenuous exercise to prevent thrombus from falling off.
